Me and a friend are doing this to just have some fun, learn a little about electronics, etc. We know we could just buy one that would look much nicer, but that isn't really the point of the project. So, the questions:
Thanks for any help!

- I don't want to kill (or blow up) my battery pack. I am using a very weak solar cell (4W, 0.5V, if I'm lucky) to charge this battery. Is that too weak to even get through the Protection Circuit to charge my battery?
- I also would like to know how I can connect my solar cell to my battery and then my phone to the battery in one circuit. How does that work? How does the protection circuit work?
- I know this site has a great resource for learning about circuits, and if you look in my history I have done all the reading commenters have asked of me, so please, tell me what to read up on, and I will get to it.
Thanks for any help!
